In the 40th Cliff Hardy book, Hardy plays a cool hand as a decades-old crime resurfaces and old scores are settled

Is Sydney gun city? It certainly seems so when Cliff Hardy is hired by entrepreneur and one-time pistol-shooting champion Timothy Greenhall to investigate the violent death of his troubled son. Soon Hardy is pitched into a world of crooked cops—former members of the Gun Control Unit—outlaw bikers, and honest police trying to quietly clean the stables. Two more murders raise the stakes, and relationships are stretched to breaking point. Hardy hooks up with a determined policewoman and forms an unlikely alliance with a charismatic biker chief. Uncovering the tangled conspiracy behind the murders takes Hardy to the Blue Mountains and Camden, to plush legal chambers, and a confrontation in an inner-west park—all against the roar of 750 cc engines.
